I'm not absolutely sure but I don't think Atlanta Cycling got flooded. Cobb Pkwy crosses fairly high over the Chattahoochee and Atlanta Cycling is uphill from the river. I've got some riding buddies that live near there that are planning to meet there and ride today. I'm assuming they wouldn't be doing that if it got flooded.
Some areas near there got hit -- Lovett School, Canoe -- but they are a little closer to the river.
